Process and Equipment

Zinc powder displacement process has 3 steps including pregnant solution purification, deoxidation and zinc powder filtering replacement.

1.Pregnant solution purification

Principle: Gold pregnant solution often contains suspended solids which should be removed before replacement. Pregnant solution purification is the process to remove suspended solid.
